Coordinates show you the position of something on a grid.
Coordinates are written as two numbers seperated by a comma. The whole thing is enclosed in brackets.
This is a coordinate: (3,2).
It represents the point that is shown by 3 on the horizontal axis and 2 on the y axis. (An axis is the line where the scales of the grid are marked).
The horizontal axis is also known as the x axis. The vertical axis is also known as the y axis.
The first coordinate always shows x the second shows y.
